Let $p : E \rightarrow B$ be a cover s.t. Aut(E) acts transitively on $p^{-1}(b)$ for some fix $b \in B$. Then $E/Aut(E)$ is homeomorphic to $B$ where $Aut(E) \subset Cov(E,E)$. The problem is that I don't even understand how the map E/Aut(E) -> B is defined, would someone please give me this definition? Apparently it is "clear" but I fail to see this.

$\widetilde{x} \mapsto p(x)$? (Where $\widetilde{x}$ is the class of $x$ in $E/\!\mathrm{Aut}(E)$.) –  a.r. Sep 17 '10 at 13:20
Thank you, I feel ashamed... –  Down Sep 23 '10 at 15:04

Funny, for a moment I thought you got this idea from mathoverflow.net/questions/39626/… but apparently that post turned up later. –  Rasmus Sep 22 '10 at 17:31
